Title: An apparatus for forming lips in strip-like material
IPC: B21D28/36
Filed: 1960-11-16
Abstract: 914,289. Punching. HUNTER DOUGLAS INTERNATIONAL CORPORATION. Nov. 16, 1960 [Nov. 23, 1959], No. 39301/60. Class 83 (4). [Also in Group I] Apparatus for forming lips 4 in a strip 3 comprises a roll 9 having radially displaceable punches 23 for forming the lips, and a roll 10 co-operating with roll 9. Metal ceiling strips 3 of curved transverse section may be formed with curved, triangular &c. lips 4 for holding curved transverse metal strips (Fig. 5, not shown). A winding drum 5 draws the strip from a reel 2, past rolls 6-8 and between the rolls 9, 10, which are rotated by the moving strip. The rolls 9, 10 rotate on a fixed shaft 13 and an adjustable shaft 12, each roll comprising two parts 33, 34 and 19, 21 respectively. The parts 33, 34 of roll 10 retain a rubber &c. rim 36 and those of roll 9 the punches 23, which are operated by a cam 24 on a guide 22 and have hooked inner ends 26 for engaging a retaining rib 27 on the guide having entry and exit ends 29, 28 adjacent the cam. Each punch forms a pair of lips 4 which may be protected by a corrugated strip (not shown), coiled on the reel 5 with the strip 3. Rims 31, 32 on the roll 9 guide the strip. In various modifications, the shaft 13 may rotate and the roll 9 may be formed in a single part.

Patent GB-995926-A (GB)
Title: Preparation of virus antigens
IPC: A61K39/29
Filed: 1962-10-18
Abstract: A virus antigen is purified by placing an aqueous solution containing virus antigen in contact with a bed of wetted, granular, hydrophilic, water-insoluble, cross-linked dextran polymer gel capable of absorbing water with swelling and having a porosity smaller than the molecular size of said virus antigen and washing the gel with an aqueous eluant to recover the virus antigen.  A chromatographic type column is used, the column is equilibrated with an aqueous medium such as dilute saline, and the impure virus solution is passed down the column which is then washed with an aqueous eluant to recover the virus antigen, the operation being carried out under sterile conditions.  Prior to treatment with the dextran polymer gel, the aqueous virus solution, previously freed from solids in the conventional way, may be treated with an inert, liquid, water-immiscible, fluorohydrocarbon solvent, which may be admixed with an inert, water-immiscible, liquid, hydrocarbon solvent of low density, e.g. n-heptane.  The solvent is mixed with virus solution in proportions of 1 : 1 and 2 : 1 and 5 to 6 extractions may be made. The gel-treated virus may be subjected to ether extraction with or without the addition of a wetting agent.  After separation of the ether phase, residual ether is removed from the aqueous phase by treatment with an inert gas such as nitrogen. Water may be removed wholly or in part from the purified aqueous virus solution by dialysis against a hydroscopic material which is separated from the aqueous solution by means of a water-permeable dialysis membrane. The ether purification step is particularly effective in the preparation of influenza virus and this may be followed by the addition of a preservative and stabilizer such as formalin.  Other viruses specified are rabies, infectious hepatitis, mumps, vaccinia, equine encephalomyelitis, canine distemper, poliomyelitis, encephalomyocarditis, hog cholera, St. Louis encephalitis, yellow fever, adenovirus, measles, Coxsackie, ECHO and common cold viruses. Specifications 802,048 and 854,715 are referred to.

The substituted benzotriazole may be 5-chloro-, 5-bromo-, 5-methyl-, 5-nitro- 4, 6-dinitro-, 1-ethyl-or 1-phenylbenzotriazole. The benzotriazole may be added in an aqueous solution of gelatin or in an aqueous solution of the water-soluble halide. The silver halide emulsion is preferably a chlorobromide or chloroiodobromide emulsion. A metal salt or a metal complex salt, the metal not being silver, e.g. rhodium ammonium chloride, may be added during preparation of the emulsion. High density, high contrast material with little fog formation is produced without decreasing the sensitivity.

Abstract: 339,144. Holzverkohlungs-Industrie Akt.-Ges. Jan. 18, 1929, [Convention date ]. Acetone.-In the catalytic production of acetone from acetylene and water vapour, the reaction gases are circulated continuously past heat exchanging walls which separate part of the circuit from a reaction zone, part being continuously diverted into the reaction zone, and the temperature being regulated by the speed of the reactants in the circuit. The reaction mixture enters at 10 and is circulated as shown by the arrows by a pump 6. A cooling device 11 is provided. A portion of the gases passes through the openings 7 in the pipes 2 and traverses the catalyst in chamber 1, the product being withdrawn by pipe 9. A corresponding quantity of the reaction mixture enters at the inlet 10.

Title: Improvements relating to the development of electrostatic charge patterns
IPC: G03G15/10
Filed: 1961-11-08
Abstract: In developing as by means of a liquid applicator such as a roller an electrostatic charge pattern on a hydrophobic surface with an aqueous liquid, which may be water alone or containing dissolved or dispersed in it one or more of a dye or pigment, a humectant such as glycerol glycol or sorbitol, a compound capable of reaction to form a coloured compound, a surface tension modifier such as an inorganic salt or an organic surfactant, a natural or synthetic organic or inorganic colloid, a water-miscible liquid of high dielectric constant such as formamide, a colloid hardener, or a reducing agent, with application of an electric field normally to the surface so that the liquid wets the surface imagewise in accordance with a pattern determined by the charge pattern (see Division G2), wetting occurs in the charged areas if the field is of 10-100 volts and in opposition to the field due to the charges, and in the uncharged areas if the field is of 100-500 volts and in the same sense as the charge field.  If the charge image is carried by a surface having rectifying properties an A.C. field may be employed with the same effects from the resulting effectively unidirectional field but increase of frequency from 50-1000 c/s. reduces wetting in the background areas.

Abstract: 1425646 Burners POTTERTON INTERNATIONAL Ltd 27 Aug 1974 [28 Aug 1973] 40514/73 Heading F4T Initiation of the lighting-up sequence for a gas burning appliance supplied with air by an electrically-driven fan 7 takes place only when a sensor 11 indicates non-existence of a pilot flame and a sensor 17 indicates non-existence of an air flow. When a thermostat 22 closes a switch 21 a relay 23 is energized to close a holding-circuit switch 23A and a switch 23B which starts the fan motor. A restrictor 19 provides a delay of about 10 seconds before the sensor 17 operates a switch S3 to energize a spark generator 25 and an electromagnetic valve 15. If the pilot flame lights, the sensor 11 expands a bellows 12 opening a valve 14 for the main burner and a switch S1. The energizing circuit for the relay 23 includes both switches S 1 and S3 so that the relay cannot start a further cycle until both switches are returned to their original positions by the sensors 11 and 17. The holding circuit for the relay 23 is broken when the thermostat opens the switch 21. The switch S1 may be replaced by a double-pole switch (S2, Fig. 3) and the valve 15 may control the pilot conduit 27.
